The Design of Rolling Bearing Mountings Part 14 docx

... on the roll- ing bearing aspects of the applications. The operation of the machine allows conclusions to be drawn about the operating conditions which dictate the bearing type and design, the ... of a rolling bearing prevents the rolling ele- ments from rubbing against each other. It keeps them evenly spaced and guides them through unloaded sec- tions of th...

... pres- sure in the rolling contact area of the bearing is rela- tively low (p 0 ≤ 2,000 N/mm 2 ), and the bearings are failsafe. Consequently, the service life of the bearings is dictated by the grease ... arranged. Bearing selection The axial load of 130 kN is made up of the weight of the rotor and the two variable top and bottom fan im- pellers as well as...

... to M6 The bearings are fitted tightly on the shaft due to the high load, which is sometimes of the shock type. This reduces the danger of fretting corrosion, particularly at the drive end. Bearing ... clearance Due to the tight fits, the inner ring of the bearing is expanded and the outer ring with the roller-and-cage assembly is contracted. Thus the radial...
